Rutherford Scattering
A great deal of what is known about the atomic nucleus has been deduced from the analysis of scattering experiments done with charged particles and neutrons. The first such experiments were performed with alpha particles from naturally radioactive substances, the counting of the scattered particles being done by visual observation of the scintillations (faint flashes of light) from a zinc sulfi...
متن کاملRutherford Backscattering Spectrometry (RBS)
Rutherford Backscattering Spectrometry (RBS) is a widely used method for the surface layer analysis of solids. This lecture gives a brief introduction into the method, and describes scattering kinematics, scattering cross-section data, stopping power data, detector resolution issues, and electronic energy loss straggling in some detail. Computer codes for the simulation of RBS spectra and RBS d...
متن کاملRutherford Scattering of α-Particles
The scattering of α-particles off of gold foil was investigated. Attenuation of the α-particle beam was used to measure the thickness of the gold foil used. The coefficient of the Rutherford differential scattering cross section was experimentally determined to be (7.81 ± 5.35) × 10−25cm2, compared to 1.76 × 10−24cm2, with a reduced chi-squared of 3.4, which is a reasonable fit and confirms the...
متن کاملRutherford Scattering with Retardation
Numerical solutions for Sommerfeld model in nonrelativistic case are presented for the scattering of a spinless extended charged body in a static Coulomb field of a fixed point charge. It is shown that differential cross section for extended body preserves the form of the Rutherford result with multiplier, not equal to one (as in classical case), but depending on the size of Sommerfeld particle...
متن کاملA 21 st century Rutherford experiment
In 1909, Hans Geiger and Ernest Marsden [1] reported on the strange behavior of α particles scattered by a gold foil. They observed a wide angular distribution that could not be explained by Thompson’s picture of an atom consisting of “a number N of negatively charged corpuscles, accompanied by an equal number of positive electricity uniformly distributed throughout a sphere” [2]. Ernest Ruther...
